Cordyceps chanhua

Cordyceps chanhua is an ascomycete fungus that parasitizes cicada larvae found in Southern China. It forms white and yellow asexual fruiting structures resembling synnema. It is known in Traditional Chinese Medicine as Chan Hua which means "cicada flower". Its medicinal uses date back to the fifth century AD in China. It can also be used in various foods and tonics. Chan-hua is previously misidentified as Isaria cicadae, another pathogen of cicada larvae. However, this name describes a fungus found in Brazil in 1838 with significant morphological and DNA differences. Other misattributed names include Cordyceps cicadae and Cordyceps sobolifera. Due to widespread misidentification, "Isaria cicadae" has been reported to exist on other continents....read more on Wikipedia.
